The 22-year-old Hunger Gamesstar even went out of her way to make sure she wasn’t seen with her former flame (though they’d arrived in the same car), asking to be escorted out the back door and through the kitchen!

As In Touch exclusively reported, the couple dated for nearly two years after meeting on the set of X-Men: First Class in 2011, but split in December 2012.

Just before calling it quits, Jennifer had spoken out about her beau, describing him as “my best friend” and saying, “He makes me laugh harder than anybody.”

Since then, the star’s won an Oscar for her performance in Silver Linings Playbook. Clearly not bitter about the breakup, Nicholas, 23, praised her publicly for it, saying, “I am very, very happy for her.”

And it seems the reunion was more of a business meeting than a rekindling of romance: The pair are currently filming their superhero sequel X-Men: Days of Future Past.
